MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has unveiled five new half-bridge IGBT power modules, offering a step forward in energy efficiency for high current inverter stages across various industries including transportation, energy, and industrial applications.
The new devices, housed in the redesigned INT-A-PAK package, are built on Vishay’s Trench IGBT technology. The modules offer designers a choice between low VCE(ON) or low Eoff technologies, options geared towards reducing conduction or switching losses. This flexibility allows for more efficient power usage in diverse applications.
IGBT, or Insulated Gate Bipolar Transistor, is a type of semiconductor device commonly used in power electronics due to its high efficiency and fast switching. It’s particularly suitable for high voltage and high current applications such as inverters, electric motor drives, and power supplies.
The newly released half-bridge devices combine Trench IGBTs, known for their superior power savings compared to other market alternatives, with Gen IV FRED Pt® anti-parallel diodes exhibiting ultra-soft reverse recovery characteristics. This combination aims to maximize efficiency in power conversion applications.
The updated INT-A-PAK package introduces a new gate pin orientation and ensures 100% compatibility with the 34 mm industry-standard package, offering a straightforward mechanical drop-in replacement. This makes the transition to these new modules easier for manufacturers and reduces the time and cost of implementation.
Potential applications for these industrial-level devices include power supply inverters for railway equipment, energy generation, distribution and storage systems, welding equipment, motor drives, and robotics. For instance, to minimize conduction losses in output stages for TIG welding machines, three of the new models offer an industry-low collector-to-emitter voltage of ≤ 1.07 V at +125 °C and rated current. Meanwhile, two other models cater to high-frequency power applications, offering exceptionally low switching losses.
The RoHS-compliant modules feature 650 V collector to emitter voltages, continuous collector current from 100 A to 200 A, and impressively low junction-to-case thermal resistance. With UL-approved file E78996, these devices are mountable directly to heatsinks and offer low EMI to minimize snubbing requirements.
With samples and production quantities of the new IGBT power modules now available and lead times of 15 weeks, Vishay’s latest offering represents a significant advancement in power module technology. By providing high-efficiency solutions, Vishay continues to push boundaries in the electronics industry, contributing to the development of more energy-efficient and sustainable technologies.
